Don't ever get involved with living social which is now owned by Groupon. Complete rip off cost my restaurant 2,500 in 3 months. They lied about everything and I'm glad there done. Had 4000 employees and then 5 years later had 200 sold to Groupon.
So please if you own a restaurant stay far away from these morons. If you want more customers just offer 10% off there bill and you will be way better off.
